The hero, a janitor played by Chaplin, is fired from work for accidentally knocking his bucket of water out the window and onto his boss the chief banker (Tandy). Meanwhile, one of the junior managers (Dillon) is being threatened with exposure by his bookie for gambling debts unpaid. Thus the manager decides to steal from the company.
A painter turned tramp (Chaplin), devastated by losing the woman he was courting as a wealthy man, finds himself drunk and getting drunker by the minute with some sailors at a bar until he's literally falling down. He keeps futilely trying to draw the woman's picture on the floor with a piece of chalk until he finally passes out cold (or perhaps dies, as in the poem) at the end of the film.
Charlie takes care of a man in a wheelchair.
